Preface of Special Feature “Current topics on cycad biology: Deciphering the Rosetta Stone of plant evolution.” Part II: Perspectives from natural history

open access: yesPlant Species Biology, Volume 40, Issue 6, Page 527-529, November 2025.
Often regarded as “living fossils,” cycads are well known for retaining many ancestral traits, which makes them particularly fascinating to naturalists and scientists alike. Cycads provide insights into the functional and developmental processes underlying the origin and diversification of seed plants, and they may help clarify how they colonized the ...

Evolutionary implications of a deep‐time perspective on insect pollination

open access: yesBiological Reviews, Volume 100, Issue 4, Page 1452-1466, August 2025.
ABSTRACT Plant pollination by insects represents one of the most transformative and iconic ecological relationships in the natural world. Despite tens of thousands of papers, as well as numerous books, on pollination biology published over the past 200 years, most studies focused on the fossil record of pollinating insects have only been published in ...

Threats to cycad biocultural heritage in the Amami Islands, Japan

open access: yesPlant Species Biology, Volume 40, Issue 4, Page 292-310, July 2025.
The central point we seek to frame in this article is that the increasing infestations of cycad aulacaspis scale in the Amami guntō existentially threaten not only the islands' sotetsu but rather entire cultural systems and natural ecologies that have developed around these plants.
